What ICD-10 Codes are Used for Coronary Artery Disease?

Coronary artery disease (CAD) is a common heart condition where the blood vessels that supply the heart with oxygen and nutrients become narrowed or blocked. Proper coding for CAD is vital for accurate medical documentation, billing, and treatment planning. The ICD-10-CM system provides specific codes for different aspects of coronary artery disease.

Here are the most commonly used ICD-10-CM Codes for Coronary Artery Disease:

I25.10 - Atherosclerotic heart disease of the native coronary artery without angina pectoris: This code is used when a patient has atherosclerotic heart disease of a native coronary artery without experiencing angina (chest pain).
I25.110 - Atherosclerotic heart disease of the native coronary artery with unstable angina pectoris: Indicates the presence of unstable angina in conjunction with atherosclerotic heart disease of a native coronary artery.
I25.111 - Atherosclerotic heart disease of the native coronary artery with angina pectoris with documented spasm: Used when the patient experiences angina with established coronary artery spasm in the presence of atherosclerotic heart disease.
